You said validation matters more than generation, so I built it
A while back I posted MetaBlast here, a tool for generating meta and OG tags. A few of the replies said roughly the same thing: people probably care more about checking the tags they already have than making new ones, and the live previews were the stronger part.
Took me a bit, but I came around to it. So I built the other half.
You paste a URL and it shows how your link actually renders on Google, X, Facebook and LinkedIn. If something's off it says what: no og:image, an image with no width/height set, a title that gets cut off, a description that doesn't match the page. When it finds something it puts a fixed version right next to the broken one. No score out of 100, those never sat right with me.
If you want to poke at it, paste your own launch page. I was surprised how many sites I assumed were fine turned out not to be.
Couple of things I'm still unsure about:
- is checking the better default, or do most people still come in wanting to generate?
- what would make this a tab you keep open instead of a one-time thing?
Here's the tool if you want to try it: https://metablast.dev/meta-tag-checker
Thanks!
This is a nice example of switching from “generation-first thinking” to “validation-first thinking.” In most SEO/meta tools, generation is the obvious core feature, but validation is what actually gets repeated usage because it sits earlier in the workflow and compounds across existing assets. The real insight here is that checking creates more recurring surface area than creating.
Yeah, that's exactly the bet, checking sits earlier in the flow and repeats, generating is more one-and-done. Curious if you've felt that pull yourself when shipping.
I have, but I don't think the interesting part is generation vs. validation.
Your reply made me think there's a bigger strategic decision sitting underneath that shift, and it becomes much more important as the product grows. I don't think I can explain the reasoning properly in a thread without oversimplifying it.
If you're interested, what's the best email to reach you on?
This is a strong pivot—validation-first tools usually win on retention because they plug into existing workflows rather than creating new ones. Most users come for generation, but stay for auditing once they see real SEO impact issues. To make this a daily tab, consider adding scheduled scans, change detection, and alerts when tags break after deploys. A Chrome extension + CI hook would also turn it into a continuous safety layer instead of a one-off checker. Nice direction overall worth iterating
Thanks, appreciate it. Monitoring and change-detection on deploy are the next thing I’m weighing. Good to hear it’s where your head went too.
